oil leak on my 2004 SRX

We changed the oil on our 04 srx 3.6 awd. I put in a new oil drain plug thinking the rubber seal
Was bad, but I am still getting drips in drive way. The car has 80,150 miles on it. Can anyone
Please advise me where to look ? The car runs excellent, the only other issue I have had the
exhaust pipes rattles a bit when the car starts.
Thank you

Anyway to get the truck lifted and look underneath. If you have the splash shield you will need to remove that. If your lucky its just could be a loose oil filter or pan gasket. If its the drain plug you may have over tighten the plug(forgot o-ring). I read the 3.6 uses a lot of oil? Maybe all the fill ups with oil have spilt down an accumulated on the shield and is finally dripping.

First I hate oil leaks that make it to the ground!
I'd think if the leak were at the drain plug it would be very noticeable.
Are you sure it's engine oil? Being an AWD the front differential could be a leak source, especially the axle seals. An inspection from the bottom, as recommended by orandaberg would be your best bet. You may get a clue by observing the leak's location on the driveway/garage floor in relationship to where it occurs HOWEVER leaks are like a roof leak. Often it runs from one location to another before it hits the ground.
BTW, item 712 in the graphic was discontinued and you probably don't have it. It's an oil level monitor sensor.
